About pollen in McKinney
Weed pollen is the only category showing activity in McKinney today, and it remains at a low level. Most people should be able to go about their outdoor plans without much irritation, though those especially sensitive to weed pollen may notice mild effects, particularly during the afternoon hours when pollen tends to circulate more freely in the air. Looking ahead, the next several days are expected to hold steady at this same low level, so no significant change is on the horizon this week. This tracks with the seasonal pattern for mid-August, as we're in the early stretch of weed season, with ragweed being the main contributor in this region and typically building toward its peak as late summer turns to fall. Tree pollen from area species like oak, elm, and pecan is long past its spring peak and isn't a concern right now, and grass pollen has largely wound down as well.
